public class DrawTopViewAntenna
extends javax.swing.JPanel

A panel that handles the display of the azimuth position of the antenna. An image is used to represent the antenna itself, while Shape objects represent the angles of the various settings and positions. The display is updated regularly to keep a constant display of the antenna's current state.

Method Detail

paintComponent

public void paintComponent(java.awt.Graphics g)

Handles the setup and display of this antenna representation.

Overrides:

paintComponent in class javax.swing.JComponent

updateImage

public void updateImage(double degree,
                        double posSSA,
                        double negSSA)

Sets the current antenna angle and soft stop positions in the display, and repaints the image. This method is called from the enclosing panel regularly to constantly display the current position of the antenna. All positions are measured in degrees.

Parameters:

degree - the angle, in degrees, of the current antenna position

posSSA - the angle, in degrees, of the positive soft stop

negSSA - the angle, in degrees, of the negative soft stop
